Description

Technical Field

[0001] The utility model relates to the technical field of building trusses, in particular to a building roof truss. Background Technique

[0002] A truss is a structure formed by connecting rods hinged to each other at both ends. A truss is generally a planar or spatial structure composed of straight rods with triangular units. The truss rods mainly bear axial tension or compression, so that the strength of the material can be fully utilized. When the span is large, it can save materials compared with a solid web beam, reduce its own weight and increase stiffness. The advantage of a truss is that the rods mainly bear tension or compression, which can give full play to the role of materials, save materials and reduce the structural weight. Commonly used trusses include steel trusses, reinforced concrete trusses, prestressed concrete trusses, wooden trusses, steel-wood composite trusses, and steel-concrete composite trusses.

[0003] Most of the existing building structures composed of trusses are rectangular roofs. When encountering strong airflows, the wind forces on each connecting rod inside the truss are strong, and a large number of fixing parts are required to reinforce it, consuming a large amount of resources. At the same time, on the premise of ensuring firm fixation, the truss structure is not easy to disassemble, difficult to carry, and not convenient to use. Therefore, we designed a windproof building roof truss. Summary of the Invention

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1-5 , a building roof truss, including a first protective outer frame 1, characterized in that: a plurality of ventilation slots 2 are opened on the outer wall of the first protective outer frame 1, and the plurality of ventilation slots 2 are distributed in a circumferential array on the outer wall of the first protective outer frame 1. A plurality of fixed support rods 4 are provided on the outer wall of the first protective outer frame 1, and the plurality of fixed support rods 4 are distributed in a circumferential array on the outer wall of the first protective outer frame 1. The fixed support rods 4 are fixedly connected to a second protective outer frame 5 on the side away from the first protective outer frame 1. Among them, by setting a plurality of fixed support rods 4 outside the first protective outer frame 1 to connect it with the second protective outer frame 5, the fixing stability and safety of the device are improved. One end of a limiting sleeve shaft 6 is fixedly connected to the outer wall of the first protective outer frame 1, and the other end of the limiting sleeve shaft 6 is fixedly connected to the outer wall of the second protective outer frame 5. An inner frame 3 is sleeved on the inner wall of the first protective outer frame 1. Among them, the inner frame 3 can protect the mesh cover placed inside it and can also effectively enhance the connection stiffness of the device, and can effectively prevent the device from falling apart. A fixed shaft 9 is sleeved on the inner wall of the inner frame 3. A support partition 8 is provided on the outer wall of the fixed shaft 9. Fixed teeth 7 are provided on the inner wall of the inner frame 3, and a tooth block body 71 is fixedly connected to the inner wall of the inner frame 3. An L-shaped card slot 72 is opened on the outer wall of the tooth block body 71. One end of a partition fixing frame 81 is fixedly connected to the outer wall of the fixed shaft 9, and an L-shaped placement plate 82 is fixedly connected to the partition fixing frame 81 on the side away from the fixed shaft 9, so that the connection stiffness of the device is enhanced. And through the sliding connection between the L-shaped card slot 72 and the L-shaped placement plate 82, when the device is maintained in the later stage, it can be loaded and unloaded through its sliding connection, making the maintenance process of the device simple. The support partition 8 is directly slidably connected to the fixed shaft 9, and the support partition 8 and the fixed shaft 9 are symmetrically distributed on the inner wall of the inner frame 3.
